Men are generally concerned about their image, especially when it comes to private issues that are difficult to talk about. They tend to blame the woman, such as infertility, which is definitely the woman's fault! Despite all this, we have to admit that infertility and gynecological problems are indeed related to men.

1. Trichomonas vaginalis and yeast infection
Many women unknowingly contract trichomoniasis or yeast infections, surprising even themselves. "I'm very clean; I change my underwear and sanitary napkins frequently, I don't douche, and I don't like using public items, so why did I still get vaginitis?" In fact, among these patients, apart from a few cases due to indirect infection during sexual intercourse, the main route of infection is direct transmission through sexual intercourse between partners.
Both trichomoniasis and yeast infections can silently hide in the husband's urethra. They generally don't bother the husband or cause illness; however, a healthy carrier like the husband can bring "disaster" to his wife. When a woman's resistance is low or the vaginal pH balance changes, these pathogens begin to multiply rapidly, with predictable consequences. Both types of vaginitis are contagious, and for complete treatment, both partners must be treated simultaneously. Sexual intercourse should be avoided during treatment. After laboratory tests confirm that neither partner is a carrier of the pathogen, a second course of treatment can be administered to consolidate the results.
2. Pelvic inflammatory disease, endometriosis
Many men, unable to bear the loneliness, demand intercourse during a woman's menstrual period. Many women, knowing it will be uncomfortable, do not refuse to satisfy these demands. Intercourse during menstruation not only increases menstrual flow but can also lead to infection, causing pelvic inflammatory disease. If the movements are too rough, endometrial fragments may be forced into the pelvic cavity, causing endometriosis. Women with chronic cervicitis, such as cervical polyps or cervical erosion, are more likely to experience bleeding during intercourse if stimulated before the condition has healed.
3. Sexually transmitted diseases
Sexually transmitted diseases (STDs) are genital infections caused by sexually transmitted infections, and are most common in people who engage in promiscuous sexual activity. If the husband has an STD, the wife is often likely to become infected as well. Therefore, in addition to avoiding extramarital sexual contact, couples should also avoid infecting each other.
